萌仔仔
[méng zĭ zĭ]
This is a very cute-sounding name for a playful, youthful or adorable online personality, emphasizing cuteness ('Meng' is often used as a term to describe cute or endearing attributes). The repeated ending '仔仔' makes it particularly sweet and informal - perfect for someone who loves all things cutesy or wants to express lightheartedness.
